OIL BURNER.

Specification of Letters Patent.

Patented Mar. 21, 1922.

Application filed March 22, 1920. Serial No. 367,899.

T o allwiwmit may concern:

Be it known that I, ALBERT T. NEWMAN, a citizen of the United States,residing at Em oria, in the county of Lyon and State of ansas, haveinvented certain new and useful Improvements in 'Oil Burners; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

This invention relates to oil burners and particularly to means forvaporizing the oil whereby the oil vapor will be mixed with air in orderto effect the most efiicient combustion ofthe fuel.

The invention contemplates means whereby the incoming fuel oil may besubjected to heat intense enough to transform it into a gaseouscondition prior to being ignited and, thereb effect an econom in theconsumption of the fuel since gasi ed oil mixed with air will produce amore intense heat than is possible when the oil is directly convertedinto heat without first passing through a vaporizing or gasifying zone.

In the drawings,

Fig. I is a sectional view through a burner constructed in accordancewith my invention, and

Fig. Ill is a disassociated view of the burner, showing the inner memberof the gasifying means in elevation and the outer member in section.

In carrying out my invention, I prefer to employ an an delivery deviceconsistlng of a conical member 1, having a relatively large centralorifice 2, through which the air may pass, and the member 1 is shown asprovided with at. outwardly and upwardly curved flange 3 to provide acircumferential groove 4 to receive oil for priming. The conical member1 is provided with a plurality of shoulders 5, illustrated as three innumber, and these shoulders constitute steps to receive the base of theinner conical member 6 of the vaporizing device.

The member 6 is adapted to be seated upon the steps or shoulders 5 andit is in the form of a truncated cone, in the top of which is provided acircumferential oove 7, and

35 there is a plurality of longitu inally extending ribs or spacingmembers 8 about the perimeter of the cone and these ribs intersect thecircumferential grooves 9 formed in the outer wall of the member 6. Thegroove 7 is formed by the end wall of the member 6 and a boss 10 in theend thereof, which is provided with an opening 11 to receive the end ofthe fuel pipe 12, whereby fuel may pass into the groove 7 and flow overthe walls of the members 6, as will be presently explained.

The cover or outer conical member 13 is provided with a heattransmitting flange 14 and said member is spaced about the member 6 bythe ribs 8 to form the wall of the member 13, corresponding in shapewith the walls of the member 6 but being large enough to the burner. Assoon as the walls of the members 6 and 13 become sufliciently heated,the oil will be vaporized in gaseous form, the valve 16 being thenmanipulated to provide the proper mixture, it being understood that theair .suppl will be substantiall constant in the oil an the gas supplywill have to be regulated to rovide the most eflicient mixture, the conition-of which can be readily determined by observation.

After the gaseous vapor is formed and the burner is in action, the wallsof the members 6 and 13 will become quite hot and the heat absorbed bythe member 13 will be distributed to the heat thereof and conveyed tothe chamber formed by the groove 7 through the depending flange 14 sothat the oil initially discharged from pipe 12 will be quickly raised toa relatively high temperature, t en as the oil flows over the wall ofthe member 6, it willbe vaporized, the rooves 9 serving to retardtheflow of the 011 so as to insure efiicient heat penetration to effect thevaporization thereof. The result will be that the fuel will be admittedin a circular sheet against the wall of the groove 4 and by beindeflected, will create a partial vacuum in t e space 17 formed betweenthe cone 1 and the inner surface of the wall of the member 6, assistingthe flow of air through the openings 2 to supply the necessary oxygen tosupport combustion.

shells constituting a vapor generating space, and means for supplyingoil to said space.

2. An oil burner comprising an inner shell having horizontal grooves inits outer wall, longitudinall disposed spacing ribs on the outer wall 0the shell, an outer shell sup ported upon said ribs, the space betweenthe shells constituting a vapor generating space, and a grooved primerin line with and below the shells.

In testimony whereof I aflix in Si nature.
